FIRE-PLACE HEATER.

SPECIFICATION forming part of Letters Patent No. 448,103, dated March10, 1891.

Application filed May 31, 1887. Serial No. 239,774:- (No model.)

To all whom it may concern;

Be it known that I, FREDERICK D. Woon- RUFF, a citizen of the UnitedStates, residing at Maywood, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement inFire-Place Heaters, of which the following is a full, clear, concise,-and exact description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to magazine-stoves for heating purposes; and itconsists in a stove havinga large radiating-surface in connection withsuitable tines and dampers so arranged that the heat generated may beutilized to the fullest extent. The stove is preferably placed near thewalls of the room, so as to have the appearance of a fire-place grate.

My heater is preferably constructed so as to take the place of thechimney-breast, and will befound especially adapted to be usedin roomshaving simply chimney-fines, and when thus arranged complete with themantel takes the place of the ordinary chimney breast and open grate. Acombustion-chamber is placed above the fire-pot, having the sideextending backwardly, and vertical partitions are placed in thecombustion-chamber, forming divisions therein. Ribs upon the back of thecombus- Lion-chamber extend diagonally from one of the perforatedextended sides upward to the other of the perforated extended sides ofthe combustion-chamber. Thus sufficientheat may be obtained to warm theroom or building in the very coldest weather. The doors are so arrangedthat they may be opened wide enough to make the fire-place act as anopen grate,when desired, or the doors may be made removable, like ablower.

I have found that cannel-coal or wood may be successfully used in myheater without a blower or other-device for closing the grate. In casehard coal or coke is used I have fonndit necessary to provide means forclosing the upper part of the grate in order to increase the draftsufiiciently to heat the radiating-surfaces.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view, partly in section, showing my heatercomplete in connection with a mantel, the blower and damper beingremoved. Fig. 2 is a front elevation showing the fines and flue-dampersin detail with doors provided for the purpose of closing the grate afterthe manner of a blower, the form of the opening being accordinglymodilied. Fig. 3 is a central transverse vertical sectional View uponline 00a: of Fig. 1. Fig. 4 is a rear view showing theradiating-surface, the straight arrows indicating the direction of theair as it circulates between the heater and the wall. Fig. 5 is ahorizontal view upon liney y of Fig. 4, showing the connection betweenthe fines of the heater and the chimney. Fig. 6 is a front view of myheater, in which I have shown hot-air pipes introduced into the smoke-chamber and connecting above with a hot-air chamber which is connectedby register with the room above. Fig. 7 is a sectional view thereof online 12 o of Fig. 6. Fig. 8 shows the hot-air fines shown also in Fig. 6and the swinging damper by means of which the smoke is sent around aboutthe hot-air pipes or directly into the chimney-flue, as desired. Fig. 9is a view of the damper asseen from line z 2 of Fig. 8.

Like parts are indicated by similar letters of reference throughout thedifferent figures.

As shown in Figs. 2 and 3, when the damper a is closed, the draft willbe, as indicated by.

from the horizontal, the opposite sides c be ing open-work orperforated, as shown. Thus it will be seen that the combustion-chamberin my heater has the appearance, as it were, of a chimney-breast,through which combustion-chamber the smoke and products of combustionare made to circulate at will by means of the vertical partitions anddamper placed therein, and this combustion-chamber, thus becomingheated,acts as a radiator both in front and in rear and serves to keepthe air of the room heated and in circulation.

As shown in Figs. 8 and 9, I provide hotair pipes 01 d in thecombustion-chamber when a room adjacent to or over the room in which theheater is placed is to be warmed thereby. These pipes are connectedbelow with a coldair duct or with the air of the room and above with ahot-air chamber 6. From this chamber e hot-air fines are led in anydirection desired. I have shown opening f provided with a register forheating the room above.

As shown in Figs. 6 and 7, the combustionchamber is divided by apartition 9. The smoke, when the direct-draft damper h is closed, willbe caused to circulate up around the said partition g into the flue t'.The pipes 61 may be round or square or of any shape desired. Ipreferably, however, make the pipes next to the partition g smaller thanthe outer pipes, as shown in Fig. 7, so that there may be plenty ofspace remaining in the combustion-chamber for the smoke to circulate. Byopening the damper h the draft is made direct to the chimney-fluewithout circulating around the partition or division g.

By reference to Figs. 1, 3, and 4 it will be seen that I provide a chuten, which extends from the door 0 at the side .down to the fireplace. Avent p from this chute connects with the chimney-flue, so that there maybe no escape of gas into the room. This chute is thus made a reservoirfor the hard coal, which is fed by gravity as needed.

The combustion-chamber is made shallow from front to rear--say three tofive inchesand of considerable width, say from three to five feet. Thusthe smoke and other products of combustion are made to come in closecontact with the walls of the combustionchamber and give up their heat,which is utilized to heat the room, as described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a heater for warming purposes, the

i of into a chimney, vertical partitions in the combustion-chamber,extending from below the flue therein and upon each side thereof to nearthe top of the combustion-chamber, forming divisions therein, a damperadapted to close the lower end of the division of the combustion-chamberwithin which the flue to the chimney is located and below such flue, andribs upon the back of the combustionchamber,extending diagonally fromone of the perforated extended sides upward to the other of theperforated extended sides of the combustion-chamber, substantially asdescribed.

2. In a heater for warming purposes, the combination of afire-pot, acombustion-chamber above the firepot, the sides to such con1-bustion-chamber extending beyond the back thereof and below the lowerend, perforations in such extended sides, a line in thecombustion-chamber, extending to a chimney, and ribs upon the back ofthe combustion-chamber, extending diagonally from one of the perforatedextended sides upward to the other extended perforated side of thecombustionchamber, whereby, when the heater is placed with suchperforated extended sides in close contact with the chimney or wall, airpassing through the perforated extension of one side of thecombustion-chamber and heated by coming in contact with the back of thecombustion-chamber may be directed to pass in such heated conditionthrough the other perforated extension of the side of thecombustion-chamber, all substantially as described. In witness whereof Ihereunto subscribe my name this 27th day of May, A. D. 1887.
